ATTORNEYS Patentedvsept. 16, 1930 PATENT FFICE rAUL G. rnrx, or CHICAGO, ILIJINOIS LAMP Application filed May 31, 1927. 'Serial No. 195,563.

My invention relates to improvements in lamps, and it consists in the combinations, constructions, and arrangements herein described and claimed.

lamp of the acetylene type which is especially adapted to be used by miners, but which may be used efliciently as a railroad lamp.

A further'object of my invention is to provide a device of the type described which has a uniform generation of gas'by providing a novel means for the uniform flow of water to My invention is illustrated in the accompanying drawings, forming part of this application, inwhich Figure 1 is a vertical sectional view of my 30 device, parts thereof being shownin elevation, and i a Figure 2 is a sectional view of a modified form of my device.

In carrying out my invention, I provide a 5 casing 1 having a lens 2 removably secured thereto by a retainer ring 3. A burner 1 is disposed in the casing 1 and is provided with a hollow tubular portion 5 which extends therethrough.

A cylindrical body portion 6 is rigidly secured to the casing 1 as at 7 and is provided with a lower threaded portion 8 and an upper threaded portion 9. A carbide receptacle 10 is provided with a threaded portion 11 at the 45 open end thereof which is receivable in the threaded portion 8 of the body portion 6. A felt pad 12 is disposed in the body portion 6 and conforms to the inner wall thereof. 'I he felt pad 12 is held adjacent the tubular por- 50 tion 5 of the burner 4 by a metal retainer 12 An object of my invention is to provide a which is disposed adjacent the upperextremity of the carbide receptacle 10.

An overflow tank 18 is provided with'a threaded portion 14 which is receivable by the threaded. portion 9 of the body portionj6. An auxiliary water tank 15 is centrally disposed in the overflow tank 13 and is provided with circumferentially-disposed openings 16 spaced equal distances from the bottom 17 of the overiiowtank'l A tube 18 is centrally disposed inthe bottom 17 and extends from a point a short distance above the openings 16 to apoint a short distance from the bottom of the carbide receptacle 10. wick 19 is. disposed ,in'the tube 18' and extends down wardly to a point substantially adjacent the a lower extremity thereof. The upper. portion of the wick extends over theupper'extremity of the tube 18and downwardly upon the outside of the tube for a short distance into the auxiliary water tank 15. v

The main water tank 20 is provided with a threaded. portion'21' which is receivablein' the threaded portion 9 of the body portion 6. An opening 22 is provided for the water tank 20 for pouring water 23 therethrough into the main' water tank 20. VA cap 24 is provided for the opening 22.

A water-check valve 25 extends through the main water tank 20 and is adapted to engage with a valve seat 26 which provides commua nication from the inain water tank 20 to the, auxiliary water tank 15, T he valve 25 is provided with a threaded portion 27 which extends through threads 28 efthe tank 20. A shut-off valve 29 extends through the water tank20 and is provided with a disoshaped headportion 30 adapted to be moved into en gagement with the upper extremity of the wick 19. A threaded portion 31 is provided for the valve 29 and extends through a threaded portion 32 in the tank 20. Hand wheels 33 and 34 are provided for the valves 25 and 29, respectively.

From the foregoingdescription of the various parts of the device, the operation thereof may be readily understood.

The water tank 20 is first filled with water and the water checkvalve 25 is adjusted to the approximate position for permitting the desired amount of water to pass from the water tank. Eetore igniting the gas from the burner, the operator makes sure that the auxiliary tank ms the desired amount oil water therein. The wick 19 is so constructed that it will permit only a desired amount of water, i. e., the amount required by the burner, to pass therethrough at a uniform and into the carbide container. As the water passes from the wick and drops upon the bide, a is formed which passes through the burner l. This may be ,ited by any suitable means, not shown.

The uniform passage of the water down the wick is dependent upon maintaining a uniform level the water in the auxiliary tank. Therefore, the wall of the auxiliary tank 15 is disposer relatively close to the wick 19, whereby the desired amount of water will be supplied to the wick, irrespective of the position. at which the lamp is held. The flow of the water through any inech airlcal valve, such as 526, is incrased throuqh any shaking oi the lamp which occurs when in use. This additional amount or wr'cr passes through the openings 16, t1 .is maintaining a uniform level of the water de sired and necessary for the uniform pas sage 0t water down the wick. The overflow tank 13 is sufficient to receive all the excess water which may pass throu 'lr. tl openings 16.

Should the operator wish to shut off entirely the supply of water to the wick, the shut-off valve 29 may be moved downwardly, thus holding that portion of the wick which extends over the upper end of the tube 18 in close engagement with the tube.

In Fgiure 2, l have shown a modified form of the water-feeding mechanism which is composed of a water tank lO having a tube 41 extending through the bottom thereof and a carbide container 12 which is removably cured to the water tank 4.0. A wick l3 c3;- tends thi ugh the tube 41 and over the u per edge thereof. A. water check alve movably disposed within the upper wall the water tank 40 and is adapted to be moved into engagement with the wick for varying the amount of water passing through the wick and cutting the entire passage of the water through the wick, it desir d, A burner, indicated generally at 45. is disposed in communication with the carbide container 42.
